I spent two silent nights here on my own. It’s a big, flat, open area in the forest. I’d expect it would be used for forestry work if there was any ongoing, but it’s also a good parking place for many walks. No notices. I walked to the Puy Pariou (looks like a moon crater), and several other Puys and Grottes. The road is busy but with slow, quiet cars. Nothing 20:00 to 07:00. 4G, just!
